I love editing OSM so much that to make so accurte I would like to to take it on the go and map on location. Who is making an OSM App for Android and IOS? Please some one start! Besides is this not what this project about, getting the mapping to everyone who can edited it. Remember this is an open project

Oh, and the MapQuest app is good for doing GPS navigation against OSM data. You just have to choose "Open" data in the preferences. I've found a number of bugs, such as non-intersecting intersections this way.
